If the number of turns per units length of a coils of solenoid is doubled , the self- inductance of the soleniod will

A tightly- wound, long solenoid is kept with its axis parallel to a large metal sheet carrying a surface current. The surgace current through a width dl of the sheet is Kdl and the number of turns per unit length of the solenoid is n. The magnetic field near the centre of the solenoid is found to be zero. (a) find the current in the solenoid. (b) If the solenoid is rotated to make its axis perpendicular to the metal sheet, what would be the magnitude of the magnetic field near its centre?

The self inductance of a coil is L . Keeping the length and area same, the number of turns in the coil is increased to four times. The self inductance of the coil will now be

A coil is wound on a rectangular frame. Keeping the number of turns per unit length constant, if the linear dimensions of the coil are doubled then the coefficient of self induction of the coil will become.

In a given solenoid if the number of turns and the length of the solenoid are doubled keeping the area of cross-section same, then it's inductance:
